Hi @wwatson
Could you please post the code or make a PR to add WiFiNINA support to FTP_Server_Teensy41, so that we can save duplication and time.
I'll try to have a look to see if there is any more bug when...
I don't see any problem with long sysex messages. Like the MIDI Sample Dump Standard you can send samples.
I've found this :
I think your real problem is the 'generic USB to Midi cable' at it uses Microsoft class...
I wanted to be sure, so I've checked the official Yamaha documentation. See page 37 here :

I posted your DX7 problem in Sequencer Forum. Look at here: https://www.sequencer.de/synthesizer/threads/yamaha-dx7iid-midi-dump.102499/
Greetings Rolf
Found this on Arduino boards: rugged-circuits.com/10-ways-to-destroy-an-arduino/
perhaps this or other things apply - given 'some signs' of catastrophe in the package seems all safety margins and components violated:
Yes. Your SysEx data block is too large. With MIDI-OX a maximum of only 2048 bytes per SysEx block can be received.
Such a large block of data is not normal. All synthesizers I know send a block of less than 500 bytes...
Since most of the questions here are quite intelligent, let me ask a stupid one.
I've been working with electronics for ...50 years at least, yet still managed to blow up a Teensy by applying 12 volts to a digital...
Hi,
I am testing it with my app in Python.
But I can see lot of noise:
If I have connected signal generator, I have no problem with noise and no problem witth all range of frequencies from 0-15000Hz:
Hi Rolf,
It's a dump of a DX7 bank with 32 patches inside. So the file actually already has only one F0, then 4102 bytes, then one F7 at the end.
In MIDIOX, I see that the usbmidi lib truncates this 4104 buffer in 266...

I wrote a small Arduino sketch and tested it on a Teensy 4.1 board.

Thanks for the reply.
I found the USB library (https://github.com/PaulStoffregen/cores/blob/master/teensy4/usb_mouse.h#L46). I assume usb_mouse_move(int8_t x, int8_t y, int8_t wheel, int8_t horiz) is the function...
On my side I managed to get it "working" with 4 channels, but I'm getting some crackling which I haven't figured out yet.

Great thanks Jay!

Thank you very much for your help, you wont believe what happened... i was such in a hurry when i connected the pins that i actually used 5v instead of ground and reversed positive with negative so instead of it going...
Note: Not sure if the one time that I thought the files was preserved was a fluke or not.

Hi @mjs513
I suggest you first try using another known-working FTP Server, such as VSFTP, ftpd, or FTP_Server_Teensy41 to be sure your Adafruit Featherwing board is working OK (hardware, nina-fw, etc). Then moving on...
I just emailed thesycon to put this project on their radar and ask for their contribution. If anyone has the knowledge to finally put the nail in this Wishlist item they definitely have it. They've written a...
It's ok and it works? :)
The next time I lay out this chip I'll be sure to read all of the PJRC page on this https://www.pjrc.com/store/ic_mkl02_t4.html. Scroll down and you'll find a great strategy for getting better...

Anyway, I just downloaded the updated...
Amazing job!
Thank you for these files as a starting point, can't wait to make my own design.
For the BGA I would've tried a heat gun soldering station... thanks for the tip with the hot plate, never seen these for...
This is my code to send SysEx to usbMIDI()
In the SysEx dump menu from my synthesizer I query a key and set the sendSyssExflag.
If the flag was true then send sysex dump. I always send a block of 348 bytes.
Then I...
Ah geez, you're right. I made those changes and now it's working. I didn't even need to mess with the sample rate with setI2SFreq() or anything. I tried with the sine wave sketch and my more complicated project and no...
Did you change the usb.c in your Arduino Library as I suggested ?
After that it is important that your project has to be completely recompiled (restart Arduino IDE).

Hello,

Hi all,

@Srx Shouldn't be hard if you have a hot-plate. Does not need to be big either. I used the MiniWare MHP30 (https://www.youtube.com/watch?v=JKlTd1B6Au8). It's tiny, but perfect for doing stuff like this & reflowing IC's....

What Arduino CPU and Windows Version are you using?
@PaulSoffregen, I'm stumped as to why this is happening. Board responds to I2C commands when the AudioOutput is PWM or others but not I2S.

If you want to eliminate any transmission delays, you can call flush() after sending TCP data when using QNEthernet. It’s possible the ArduinoModbus API needs to be changed to support this. Without calling flush(), data...
Been able to reproduce this with the following sketch:-

Wiring is correct and a card is present.
Card type: SDHC
Under the hood, incoming data is handled with callbacks, but with polling and not interrupts. The stack is polled for input every time Ethernet.loop() is called, which happens in a number of places internally, and also...
Thanks for responding! I just tried adapting the newer usb_audio.cpp file with the FrankB patches, but am still getting the clicks. Instead of the Audiotiming library (which is missing from FrankB's Github), I tried...
Yes, that’s correct. I chose “buffer if it can” over “send always” because lwIP’s API is similar, so I basically just did a direct mapping. Plus there exists that flush() call in the Arduino API (I don’t really...
Posted code ref to Paul's is worst case - as CACHE or not - it runs end to end of all PSRAM writing values, then a second loop confirming those values are present as expected. So it will blow though the cache. That...
Okay so what I am seeing is by design, just call flush whenever data is time sensitive and if not, I can let the library buffer and send the data when the timer hits to be more efficient? I will try using flush and make...
HI All,
Please use the new WiFiNINA_Generic releases v1.8.14-5
I've been testing many times and still uploading OK, without losing data.
Will update the forked WiFiNINA later, if necessary.

Call flush() to send any buffered data immediately. For reference, see the “Write immediacy” section in the Readme.
There’s no equivalent for setSocketSize() or setStackHeap(). Those are specific to how...
I tried making the switch over to QNEthernet this week but I had a few issues/questions.

You really should write some small test programs using the ARM cycle counter to measure the actual speed. When you test, use "volatile" on the variables or pointers your code uses, so the compiler doesn't optimize away...
Wow is right. I have spent the last two weekends working on FTP_Server_Teensy41 and WiFiNINA. The problem is with data.connected() always shows 1. Using the same library with QNEthernet would show data.connected() going...

The last portion of the recently completed batch of Teensy 4.1 is still en-route to Sparkfun and Adafruit. Both sites are allowing backorders. Placing a backorder with them is by far your best chance to get a Teensy...

I've tried all your suggestions, unfortunately I'm still stuck with no complete bank dump.

If you disabled in usb.c the usb midi flush output() you have to after midi data has been sent, a flush() must be sent.
This function forces the USB layer to send the data immediately. Since the USB bus is not...
When I use FrequencyMeasure on an LC, I am getting 60hz mains as a reading (LC powered by USB on a desktop pc) while testing the circuit. To me, this shows that any fluctuations on the power/ground line will be echoed...

It depends... It is slower than the other memory locations, but again it depends on your usage. In particular how often you read/write to cache versus how often does it actually have to read/write the actual physical...

You are reading the RMS result thousands of times a second even when it is not available. Try changing your loop function to this:
void loop()
{
if(rms1.available()) {
x = rms1.read();
if(x != 0.0 && s ==...
You probably need a switch circuit after the voltage regulator and before the Teensy that only switches on when voltage has reached 3V.
If that was not clear the switched voltage will supply the Teensy when up to at...
